Analysis of Entropy Generation in Diffusion HTAC Processes

Deodat Makhanlall and Peixue Jiang

Abstract—Thermodynamic irreversibility significantly limits
fuel energy conversion into useful work. Hence, the evaluation
of thermodynamic irreversibility is an important aspect in the
development of combustion techniques for better fuel utilization.
This evaluation is performed for the HTAC (high-temperature
air combustion) process through entropy generation analysis.
The primary irreversible processes of HTAC are determined
and the influence of key operating parameters such as the
combustion air temperature, and oxygen-dilution are studied.
